About
Obsidian is one of the most powerful personal knowledge management tools available, built on the principle of local-first, markdown-based notes that you truly own. Its standout feature is bidirectional linking that creates a web of connected thoughts, visualized through an interactive graph view. Obsidian's massive community has created over 1,000 plugins, including numerous AI-powered tools for writing assistance, chat with your notes, smart connections, and more. The platform appeals to researchers, writers, students, and knowledge workers building comprehensive personal knowledge bases or 'second brains.' While the core app is free, Obsidian offers paid sync and publish services.
